granted to me Sept. 5, l922,.and Nov. 28,

1922, respectively, a method for forming a container by expanding a tube and a container made by this method are disclosed and claimed. The invention disclosed in this application is an improvement on the inventions disclosed in the above mentioned patents and discloses an improved blank for a tube to be expanded into any desired form, the blank being slit to produce a desired shape when the tube formed from the blank is expanded. Several different shapes and results areobtainable depending on the form and blank used.

In producing a bilged barrel or other form in accordance with the present invention a blank is first provided with slits at predetermined spacings. The blank is then coated on one side for mostof its length with an adhesive. It is'then wound into a tube of the desired diameter and thickness ofwall with the slits either in or out of register as predetermined, and this tube is then expanded by internal pressure before the adhesive has set, until the side walls of the tube conformed to the shape of an outer separable form of the required contour, to form a container.

The blank 1 for a tube, shown in Fig. 1 is provided at equally spaced distances with saw tooth slits 2 between the side edges of the blank, the spacing of these slits in relation to the length of the sheet is such that a predetermined number of spaces and slits will equal one turn and a fraction of the nextturn on the tube. When wound as shown diagrammatically in Figs. 19, 20 and 21, this will provide a tube in which the slits will not fall 7 one over'the'other-before a certain number of layers have been wound, thus providing a tube in which the strips or panels overlap one another for a predetermined number of turns (see Fig. 10) and this type of tube is expandable into a container having imperforateside walls (see Fig. 14).

Altho I do not limit myself to the serrated edge type of cut as I show by the straight cuts shown in the blanks illustrated in Figs. 3, 5 and 42, the serrated or saw tooth cuthas several distinct advantages (see'Figs. 8 and 9). As the saw teeth out or tear thru the paper 1, in forming this slit at an angle to the plane of the paper, the paper is torn so as to form a slit with two overlapping edges. The angle at which the saw or cutter is set determines-the angularity ofthe cut; that is,

the angle which the edges of the slit make with the plane of the paper. As the cutter passes thru the paper it has a tendency to tear the paper apart so as to give a serrated cut with two overlapping edges. As the blank with this type of slits passes between the adhesive coating roll X and the roll Y which holds the paper in contact with the adhesive applying roll X, the overlapping edges, of the saw tooth or other form of serrated slit close one upon the other and prevent the adhesive being forced through the slit onto the other side of the blank.

Another advantage of the serrated edges is that when the tube is expanded into shape and the slits are in open formation, the edges of the slits do not tend to lift away from the surface to which it is intended they shall adhere as each of the serrations constitutes a separate tab having thin edges with very little spring of the material tending to lift it away from contact, whereas with the straight cut the tendency is to spring back at the edges if an adhesive of the same degree of tackiness is used as is used with the serrated out.

In Figs. 4 and 5 is shown a blank in which the end cuts 3 are in staggered relation to the medial cuts'2. The object of this is to increase the amount of sheet material between the end and medial cuts so as to prevent any tearing across the material between these cuts when the tubes, formed from these blanks, are expanded into the desired form.

Another object of placing the end slits in staggered relation is to provide a blank in which the inner ends of the slits 3 extend beyond the outer ends of the center slits 2 as shown in Fig. 5; that is, to provide for overlapping of the slits.

In most cases as shown in Figs. 1, 3, 4, 5, 6, 7 and 33 the slits 2 are interrupted throughout their length by the connecting tabs 5. These are provided to prevent the slits from opening up during the coating and tube rolling operations. The blank, after slitting,

' passes to the coating rolls where an adhesive material is placed on one side ofthe blank. The blank is then wound into a tube. The blank will be difiicult to handle if it does not have these tabs and if the cuts are sufficiently long, for the slits open up, and sagging and tearing will result. The tabs, however, placed at the required intervals, retain the edges of the slits together to allow for the manipulation of the blank. On expanding, the tabs give way, the edges then separate, and the tube takes the required shape.

When the medial slits 2 are short as in the blank shown in Fig. 2, these tabs are not necessary.

It is obvious that a number of blanks of desired length can be formed from one length of sheet material. The slits or cuts separating each blank from adjacent blanks can be, of course, either straight or saw-tooth cuts.

When it is desired to make a container having a continuous imperforate wall 7 (see Figs. 14,15 and 16) the blanks shown in Figs. 1, 2, 4 and 6 are wound into a tube of the same diameter as the smallest diameter 8 of the article to be made, with the slits 2 and 3 in staggered relation to those of the under layers, as is shown on Figs. 10, 12 and 13. This tube is then placed in the expanding machine and while the adhesive is in an unset condition, the desired article is formed (see Figs. 14, 15,16, 35, 38 and 41). I

Fig. 38 shows one type of container where the medial portion is imperforate and the end portions are perforate. This is made by winding a blank similar to that shown in Fig. 7 into a tube so that the end slits of each lamina register, while the medial slits, being of a different spacing than the end slits, do not register. This tube is then expanded. Such a barrel can be used as a ventilated barrel by utilizing a head 11 of slightly larger diameter than the diameter of the end portions. The head will then force the end portions apart. In'Fig. 38 such a head ll is provided. than the seat 9 formed to receive the said head. By forcing the'head into the seat the slits 3 are spread apart to form ventilating openings. By using a head seat of the normal diameter a non-ventilated type barrel is formed.

It is apparent that by correctly spacing the end and medial slits, the end slits can be made not to register and the medial slits to register to form an additional type of ventilated barrel where the end slits allow for expansion to form the seats or beads as may be desired.

To make a container such as is shown in Figs. 17 and 18, the blank shown in Fig. 5 is rolled to form the tube illustrated in Fig. 11 and this tube with all of its slits 2 and 3 in each consecutive layer in register is expanded into bilge formation. Added strength may be given to the structure by the addition of either 'an'interior 13 or exterior 12 hoop or hoops or the two used in conjunction, at the medial portion. 7

\Vhen it is desired to form the articles in multiples as is shown in Figs. 22 and 35 the blank is a series of connected blanks which are wound into a tube as illustrated in Figs. 24 and 34 and as the tube is expanded under pressure the blanks separate due to the tube shortening as it is expanded and the tabs 0r interruptions 27 to the longitudinal slits 28 separate. The slits may be serrated as shown in Fig. 33 In an article such as is shown in Fig. 25 it is necessary to again sever the the tube at the lines 29 to obtain the article shown. When the article is expanded at the desired point of separation as is shown in This head is of greater diameter Fig. .35, no additional separating operation is necessary. 1

It is desirable, where the source of production and consumption is widely separated to ship and store empty containers in compact formation. lVith this object in view, a container such as is shown in Figs. 26, 28. 30 and 47 can be formed, divided at the medial portion and the separate halves nested one within the other as shown in Figs. 27 and 31. hen it is desired to assemble the parts into a unitary structure the two halves are placed with the edges 14 of the side walls 7 in concentric contact. The ring 15 is then placed in position and the adhesive with which the contacting faces have been coated is allowed to set. One enclosure 32 is inserted until it rests on the seat 31 and the ring 30 is fastened in place to hold the end closure. The container is then filled with the desired material and the other end closure 32 is inserted and secured in place by the ring 30, thus makin a complete container of the bilged type.

The ring or band 15 may be placed on the inside of the container as is shown in Figs. 29 and 30, if desired, or dispensed with altogether as shown in Fig. 28, where one half of the body portion is necked or constricted at 19 to fit within the body portion 20 of the other half,

Fig. 47 shows one type of dismountable type of container where the supporting ring 15 is placed on the outside. In this case the abutting portions of the container are necked so as to form a. receiving seat for the ring 15. The advantage of this is that a smooth exterior surface for the barrel is maintained.

In the diagram shown in Figs. 19, 20 and 21 is illustrated one manner of obtaining a substantially correct spacing for the slits in a blank where it is desirable they shall not register when the blank is wound into a tube. In Fig. 20 L represents minimum diameter and K the maximum diameter while M is the mean diameter of the tube of several convolutions. Knowing these diameters the circumference N corresponding to the diameter M is readily obtainable. This is then taken as the length of the base line P in Fig. 21 and this line is evenly divided into any number of desired spacings, shown in the diagram as six and hereinafter spoken of as of that number. One of these spaces is then divided into an equal number of parts governed by the number of turns that the blank is to make when wound into tube shapebefore one of the slits will register or nearly so with one of the preceding slits in the next inner layers, in this case three. This subdivision R of the slit spacing is then again divided by the number of the major divisions I, in this case six, and one of these divisions.H is added on to each of the major divisions I and the total length J is obtained. In the case illustrated, when the division has been and illustrates clearly themanner in which the slits overlap forming the tube. a

In the diagram in Fig. 32 is illustrateda method of obtaining graphically the Spacing in the consecutive layers register one above the other in each succeeding layer as in the type of container shown in Figs. 17, 35, 38and 41.

Instead of basing the divisions on the mean circumference of the tube, as in the previous case, the outside circumference is used for the base line 1 and the inside circumference is used for the peak line6 and with both of these lines starting at XX and running parallel to each other, the lines 1, and 6 are then each equally divided by the number of slits require The line X-X is then equally divided-by the number of layers in the'tube, in thiscase six, and cross lines are drawn parallel to the base line from these points. If the equally spaced points on the peak line indicated on the diagram as A, B, C, D, E, F are now connected by straight angular lines with the equal divisions A, B, C, D,,E, F, on

the base line, the-divisions for slitting the of the slits where it is desired to have them 7 complete blank and for each turn will be obtained, and these slits will register when the tube is wound. It will be seen that the first six slits of the blank are spaced as on line 6 and the next six as on line'5, etc., until thirty-six slits'are made for the entire blank, the last slit being the end of the blank.

In some cases'where it" is desired to prevent the oozing of adhesive thru the slits, a blank with slits that do not penetrate the full depth of the blank is 'providedas illustrated in Figs. 45, 46 and 48. These slits remain closed while theadhesive is being applied, while the tube isbeing wound and until the expanding pressure is applied to form the container, whereupon they open allowing the tube to take thedesired shape.

I slit the blank only at the portions where v expansion of the tube, which is formed from said bank, is to take place. The tube when expanded in the machine increases in diameter at the points of expansion and the slits permit this expansion to take place. It is obvious that slits may be provided even at the points where no expansion is to occur as shown in Fig. 41. In most. cases slitting,

except where expansion isto take place, is not preferred, although it may beresorted to under some circumstances. V 1

In' cases where the container is not subjected to severe strains the end closures illustrated in Fig. 49, maybe used. An annular groove or channel 21is formed in the side wall 7 of the container, the lower edge of the groove being in line with the top face of the head or end closure 22. The disk forming the end closure is placed in position, resting on the head seat 18, and a fillet of heavy liquid or paste material 23 having adhesive and hardening qualities is placed in contact with the head and the grooved side wall of the container, and when this has set it acts as a locking ring for the head or closure. Such an enclosure would hermetically seal the container.

In the container closing means shown in Fig. 50 the same type of head seat, side wall and groove is used as described for Fig. 49 and the end closure or head is made up of two concentric disks, the larger or bottom one 22 is placed on the seat 18 and a ring member 24 is entered into the groove and forced to lie flat on the upper face of the disk 22 with its inner edge resting against the upper disk 33, which is preferably adhesively attached to the head disk 22. The

v perforations.

thin disk of sheet material 25, which may be in the form of a printed label,is then pasted to the disk 33 and to the head holding ring 24. To remove the head made .up of the disks 22 and 33 it is only necessary to sever the label around the outer edge 26' of the disk 33 and remove the looking ring 24. The ring 24: is made easily from sheet material folded back on itself.

The edge along the line of fold fits into 21.

material, as in Fig. 53, coated with adhesive,

into a tube. The tube is then longitudinally slitted by means of a cutting tool. The tube is then expanded into shape as shown in Fig. 51.

The best sheet material for practical commercial purposes at the present time is paper or any other similar fibrous material. Ob- Viously other sheet materials may be used, such as, for example, wood veneer, fabrics, or metal foil.

While the invention may be used for innumerable forms, some of which are illustrated, the form most useful is the bilged or barrel form. 7

Many ways of forming weakened lines at which places expansion is to take place will suggest themselves to those skilled in the art. Some of the preferred forms have been illustrated. Another form maybe a'line of I do not limit myself to the particular typ of slit except as is specified in the claims that follow.
